This invention relates "to heating, ventilating, and air conditioning devices "for domestic and commercial use, and particularly includes'a corn- 1 Claim. (01. lit -3'3) bination baseboardsuch as used as trim around the bottom of a wall, and in particular, the invention relates 'to'aba'seboardwhich also forms a radiator, and which is provided with longitudinally disposed channels for distributing he'ait,'with escape openings in the upper "edge, and with a supply duct communicating with the channels and leading from a furnace or the like.

The invention also includes "cold a'ii'r "return ducts, wherein cold air is drawn from 'ope'nin'gs between the studding'of a wailland carried "tothe furnace, providing fresh air return means.

- The purpose of this invention is to facilitate distribution of heat and cold by withdrawing cold air from a wall and supplying heated flair continuously around the baseo'f 'aw'all, whereby 'the heatedair is "evenly distributed over theentire room or enclosure.

Various attempts have been madeto provide heating and cooling elements in walls ofbuildings and in combination with baseboards, but these are usually localized at some particular point, as under a window or the like, and this does not eliminate cross currents, and particularly cold air currents across the floor.

With this thought in mind, this invention contemplates continuous hot or cold air outlets positioned around the base of the wall end incorporated in the baseboard so that the incoming air is evenly distributed.

The object of this invention is, therefore, to provide an improved baseboard for building walls which is substantially hollow and which is provided with longitudinally disposed bafiies for carrying the air from a point of supply to outlet openings distributed along the upper edge of the baseboard.

Another object of the invention is to provide an improved heating system, whereby heat is distributed continuously around .the base of walls of a building through a baseboard on the walls that may be incorporated in buildings now in use.

A further object of the invention is to provide an improved heating system, whereby cold air is drawn from the inside of the Walls of a building, heated, and returned to the interior of the building through perforations in the upper edge of a baseboard which is of a comparatively simple and inexpensive construction, and economical to opcrate.

With these and other objects and advantages in view the invention consists of the new and useful combination, construction, and arrangement of parts 'as hereinafter more fully described, set forth in the claims appended hereto, and disclosed inthe accompanying-drawings"forming part hereof, wherein:

Figure 1 is av iew 'fllus'tra'ting a section through the wall of 'a building taken on'line |-'l of Figure v3, 'with return alndv supply 'air ducts extending to a furnace 'or theflik'e, andwith'p'arts broken away.

Figure 2 is a 'siinilar'v'iew'taken on linef2- 2 of Figure 3, also with parts'bro'ken away.

Figure 4 is a sectional fplan taken on line '4-"4 of Figure 3,wi-th parts broken away, illustrating the relative positions of the parts and showing the inlet ends of the c'oldair ducts.

Figure 5 is a similaryiew on an enlarged scale, showing the upper edge of the baseboard with the "other part omitted, and with parts broken away.

Figure 6 is a longitudinal section through the baseboard taken on line 6-6 of Figure 5.

Figure '7 is a cross section through the baseboard taken on line of Figure l, with the bafiles omitted. Referring now to the drawings wherein like reference characters denote corresponding parts, the improved heating and air conditioning system of this invention includes a baseboard H), an air supply duct H, cold air return ducts I2, and a furnace or refrigerating unit l3.

The baseboard I0 is constructed as illustrated in Figure 7, with front and rear walls and with the lower edge of the front wall connected by a Pittsburgh joint M to a base I5 of the back or rear wall l6, and with the upper edge or cover connected by a similar joint I! to the upper edge of the back.

In the design shown, the upper edge or cover of the baseboard is provided with an arcuate section I8, and an upper bead or surface I 9, and the upper surface is provided with perforations 20 which provide escape openings for hot or cold air supplied to the baseboard by the duct I l. The interior of the baseboard is provided with parallel, horizontally disposed, transverse bafiies 2|, as illustrated in Figure 3, and these bafiles are centered on openings 22 through which air enters the baseboard from the duct II, and these baffles extend outwardly a considerable distance from the openings with the ends staggered, wherein the lower bailles carry the air a considerable distance from the opening, whereby the air is distributed along the baseboard.

The upper edge of the baseboard may be formed of any other shape or design for the purpose of ornamentation, and the outer surface thereof may also be formed in different shapes and designs.

Although it is preferred to make .a baseboard of thin sheet metal, it will be understood that plastic or any other suitable material may be used.

The ducts II are positioned at spaced inter vals around a room or enclosure, and these extend through the floor 23 and supporting means therefor, and connect with a continuous duct or supply header 2-4 which is connected by. a duct 25 to the hot air discharge or jacket of a furnace or refrigerating element 13. The cold air may be drawn in from the outside in the usual manner, or may be supplied through floor openings, or, as illustrated in the drawings the cold air may be supplied by ducts 12 that are positioned between the studding 26 of a wall 21, and with the lower ends connected to a longitudinally disposed duct or return header 28 that may be connected to the furnace or cooling unit l3 by a duct 29. It will be understood that although the cold air or intake ducts 12 extend into the interiors of the walls, these ducts may also be connected to air openings associated with the baseboards or other parts of the building structure.

With the parts arranged in this manner, the system may be used for air conditioning or heating, and the cold or hot air may be supplied from a refrigerating unit or furnace of any type or design. The air is supplied from the unit to the baseboard through the ducts l l, and is distributed lengthwise of the baseboard by the bafiles 21, so that a continuous supply of hot or cold air is supplied to the room through the perforations 20.

It will also be understood that other modifications'may be made in the design and arrangement of the parts without departing from the spirit of the invention.

What is claimed is:

In a heat circulating unit, the combination which comprises a hollow base board having front and rear walls connected at the lower ends with a base and having a cover with outlet openings therein, said rear wall having spaced inlet openings therein, longitudinally disposed distributing bafiles of varying lengths positioned in the base board and centered on the said inlet openings of the rear wall thereof, the length of said baflles being reduced from a lower baflle upwardly, a supply header positioned below the said base board, connecting ducts extended from the said supply header to the inlet openings in the rear wall of the base board, a return header positioned below the said supply header, return ducts adapted to extend from the said return header to points in a wall against which the said base board is positioned, and branch ducts for connecting the said supply and return headers to a heat exchanger.
